mailform virker ikke

Der kommer ingen mail frem, sen skriver at den er sendt, men det sker ikke. Nogen der kan se hvorfor?


<?php

if(isset($_POST['mailform']) && !empty($_POST['inputname']) && !empty($_POST['inputemail']) && !empty($_POST['inputaddress']) && !empty($_POST['inputid']) && !empty($_POST['inputpostcode']) && !empty($_POST['inputcity'])) {
$recipient = "mail1@ofir.dk";
$subject = "Emne";
$message .= "$_POST[inputid]\r\n";
$message .= "$_POST[inputname]\r\n";
$message .= "$_POST[inputaddress]\r\n";
$message .= "$_POST[inputpostcode] $_POST[inputcity]\r\n";
$message .= "$_POST[inputcountry]\r\n";
$message .= "$_POST[inputtelephone]\r\n";
$headers = "From: $_POST[inputname] <$_POST[inputemail]>\r\n";
mail ($recipient, $subject, $message, $headers);
header("location: ".$_SERVER['PHP_SELF']."?id=kontakt&msg=ok");
}elseif(isset($_POST['mailform'])) {
$msg = 'Udfyld venligst alle felterne med *!';
}
if(isset($_GET['msg']) && $_GET['msg'] == "ok"){
$msg = 'Beskeden er sendt!';
}
echo $msg;
?>
